it only does it when hot could it be starter selonide coz it turns over fine when cold or cooled down it only does it if you been out in it turn it off and try to start it it wont turn over but leave it for a while and then try again and it turns over and starts fine

Faulty crank sensor won't stop engine turning over.

When stuff gets hot the resistance goes up and bad connections show more. :y

seen this before on a citroen bx years ago and it turned out to be starter solenoid. and once all had cooled down it worked again.
